Thanks guys, I talked with an old Monaco factory guy and he said yes, it left the factory with a fiberglass roof and yes, they will give a little. I just got confused when a website described the fiberglass as "solid". I'm adding a Dish Hopper 3 receiver and I need to add a co-ax for it to work. Got the new cover plate and some Dicor on the way. Now if that damn white stuff would quit.
